A North Dakota man accused of killing his three daughters was back in court Thursday for another hearing, and this time he changed his plea to guilty while maintaining an insanity claim.

Aaron Schaffhausen, a construction worker from Minot, N.D., faces three counts of first-degree intentional homicide. His daughters, 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia, were found dead in their beds July 10. Their throats had been slit, and gasoline had been poured in the basement in an apparent attempt to burn the house down.
